Exam UiRPA topic 1 question 35 discussion

Developer will have to go with list because HE doesn't know how many employees details SHE gonna enter

A make since you don't know in advance how many employee ID you need to store

Answer is A because there is a "-" between integer which makes it a string. And a size of new employee is not fixed therefore we will use List<String> instead of Array of string

Because they are all of the same category(numbers) we used list of string,,,if they were numbers mixed with letters, it have to be array

List<String> because the "-" dashes turn them to be Strings. The question mentions "integer form" as a distraction to trick you into picking "integer" as the answer. List of String versus Array of String? Which is better? Remember that only Lists have dynamic size. That means you can add employee ID's to them in a "For Each" loop, one by one. It's much more difficult to do that with Arrays, because Arrays have fixed size. You add a value to an Array of 5 items, so now you have 6 items total. Check the length of the Array, and it will tell you that you still have 5 items in there. You can write janky code to manually update the size of the array to 6, but it's obvious that is not ideal when Lists have this functionality built-in already.

should be Int32 because those ID are intergers list of string, for sure can't be because id is int32 not string

Helllo fletchm58c. could you please add your input on it?

Since X is an integer so ans should be Int32[]. If someone can clarify on it is appreciable.
